The house is just a regular villa without any extra soundproofing so when other guests stumbled in at one o'clock superdrunk everyone hears it. The guests then locked themselves in both bathrooms and started violently puking for everyone to hear. One other guest were sleeping off the whiskey in the living room couch. In the morning we opened a window and it turns out the street outside has surprisingly heavy traffic.
We mailed the owner the morning after about the puking drunks and he asked "but what did they say when you confronted them?" Well, my mama didn't raise a dimwit so I'm not about to confront any drunk unknown people in the middle of the night. We could of course have called the owner in the night, but I'm not sure how that could have helped.
The house was clean and neat, but it was a far way from sights or town centers.
